Diamond drilling of concrete - the nuances of the work
To create holes in the walls used specialized equipment for diamond drilling holes in concrete. This procedure is shock-free and practically silent, does not affect the integrity of the structure. Thus, it is the only way to create holes in panel houses and buildings for various purposes.
Key points in the diamond drilling process
This technology has a certain number of features. Consider them in the table below:
| Key points of the drilling process | Special features |
| The holes are drilled using diamond ring crowns. | Ring crowns look like hollow tubes, on which carbide cutting elements are soldered, in this case from industrial diamonds. For maximum efficiency of the equipment used, the crowns should be correctly selected based on the material properties and power of the drill. |
| Diamond drilling holes in the concrete involves the supply of tap water. | This technology is used to cool the working segment - crowns, and also prevents the formation and accumulation of dust on the crown and inside the tool. |
Note! If we are talking about drilling at shallow depths, the crown simply does not have time to heat up, so the process can be carried out without pumping fluid.
| High speed. | Depending on the strength of the concrete material, the speed can reach from 1 to 6 centimeters per minute, which is a very good result. |
| Using a special bed. | In order to carry out drilling with maximum accuracy, it is necessary to fix the installation with the help of a bed on the treated surface. Anchors or a vacuum plate are used for this. |
Note! Fastening the drill is especially important when drilling holes of large diameter, allowing you to achieve high accuracy and greatly facilitating the work.
The advantages of this drilling technology
Diamond drilling of reinforced concrete has such advantages:
- The ability to work as soon as possible (on average, one hole takes about 10 minutes of time).
- Perfect roundness of holesnot requiring additional grinding. High dimensional accuracy.
- There is no dust emission in the process., and therefore the procedure can be carried out in conditions of maximum purity.
- The procedure is silent..
- Diamond drilling in concrete can be done at an angle and in the most inaccessible places and great depths..
- The ability to handle a wide variety of materials, including concrete, reinforced concrete, asphalt, marble, brick, granite, rubble, as well as any kind of artificial stone.
- By drilling a few holes, it becomes possible to create an opening. For these purposes, the cutting of reinforced concrete with diamond circles is also carried out.
- It is possible to drill holes up to three meters deep..
- The ability to drill openings in the vertical and horizontal planes.
- Large diameter range of diamond crowns (24 - 650 mm).
- The most environmentally friendly technologyand the price of the technology itself is relatively acceptable.
- During the work, damage to the facade or interior finish is excluded..
- The process requires minimal training..
Preparatory stage
Complexity and literacy of the preparatory stage are able to provide significant drilling efficiency with their own hands.
For the proper organization of the preparatory work there is such an instruction:
- The area is freed from building parts, tools and debris.
- Next, you need to make a breakdown of the axes and diameters of the proposed holes.
- Water, electricity and compressed air are supplied to the drilling site (using pneumatic drilling machines).
How is diamond drilling performed
Diamond drilling of holes in concrete is carried out as follows:
- We fix the special equipment on the processed surface. For this is usually used anchor system for concrete.
- We select the appropriate crown, depending on the planned diameter.
- Depending on the scope of work, it is necessary to determine whether a pumping fluid is needed. If the equipment needs cooling, then the system is connected to the water supply.
- The process itself is carried out directly.
Conclusion
High efficiency of this technology is a consequence of the use of special equipment. Most often such equipment is electric, but the modern market can offer the consumer and manual drills. And although the range of their use is very limited, in some conditions such hand-held devices are simply indispensable, for example, in places where there is no power source.
Electric drilling rigs differ mainly only in the diameter of the holes. Universal models are designed for drilling holes in concrete surfaces with a diameter of up to 102 mm.
If you need to drill a larger hole, then you will have to use high-power equipment, which is characterized by a large number of revolutions per minute. The maximum hole diameter that can be obtained using this technology is 500 mm.
When buying such equipment, you should pay attention not only to its technical characteristics, but also to its weight. As a rule, more expensive drilling rigs weigh less, which greatly simplifies the process of their strengthening on the treated surface.
